I've been down to about 19 degrees F. But I've also been up to 120 degrees, so I consider that a Fahrenheit Century.

I hadn't thought about that! 5-109 F is my Fahrenheit century!

I could use some warmer tights, but doubt it's worth the price (and the probability I'll lose them before it gets this cold again). Much over 100, though, maybe I should rig up one of those battery-powered spray bottles the kids used to have for swim meets on my bars.

I just bested my personal low by 2*F (new record -16*F) this week. I have a fairly short commute (2.5 miles), so the cold is just beginning to encroach by the end (mainly my fingers). When I had to go across town at -13*F on Wednesday, I hopped a bus when I could no longer feel my fingers while riding.
